A'LLiWHOM IT MAY CONCERN: Be it know-h that L .AcoB B; MOORE, of New York, in the county and Stato of' New York, have invented anew and useful Improvement in Window-Shade Fixtures; and I doyhereby declare that the following is a full, clear, and 'exact description thereof, which will enable others skillcdiuthe art to make and use the same,

reference being had to the accompanying drawing, forming part of this specificatie-n. The gurerepresents'a window to which-my improvement has been attached. My invention has for its-object to furnish a simple, chenp,'and effective window-shade fixture, which will not be liableto get out of order, and which will obvia'te the annoyance now so generally experienced from the ordinary shade-fixtures getting out of order; and it consists in the construction, combination, and arrangement of the various parts,as Ahereinafter more fully described.

A represents the window-casing, B is the roller to which the shade C isattaehed, and around' which it. is n'o'und.4 From thei'ends of the'roller B project rods D of smaller diameter than s aid roller to which rods .the cords E are attx 1c'-.h`ed, by which the'shade is supported, said cords being woundseveral'times around the said frodgin the direction shown in the drawing. By this4 construction and arrangement, the roller-1B being suspended by the cords E, the tendency is for'the roller B'to roll downin'tho direction te unwindthe cords E from therodsjD, rolling'the ourtain C up around the said roller. But the shade boing lef!l free, the tendency'of the lhldelC is te unwindor roll'the roller in the opposite' direction. To establish an equilibrium between these two forces, a rod-f?, equivalent weight i'silaced in os attached to the lower-part of tiro skoda-which should `he of such a weight as te exactly balance the said forces, so that the said shade may be placed at any part of the window without changing its position. If, now, the equilibrium be destroyed by raising the vbar or rod F. with the hand, the roller B will roll 'down upori'tho cords E, winding up the shade C` and if the equilibrium is destroyed by drawing the bar or rod F downward, the shade will be drawn down or unwound from the roller, i 'soos to cover or shade alarger part of thewii'ulew't In case tlio window-casing is sufliciently wide to allowthe shade C to beunwound without lowering theroller so far as to uncover the upper part of the window, the upper ends of the cords E nfay be attached to hooks or other supports secured to the upper part of thc casing. But in ordinary cases, (and this construction I prefer-,lille cords E'rnay be passed through eyes G, or' around guide-pulleys to the central partef the window, at which point they descend, and to their lower ori're'e ends should be'attaohed a weighted tasseLH, of auch a weight as to exactly balance the roller B and shade C. This'- enables the shado'whenfully rolled up, or when u nrolled'to any desired extent, to be raised er lowered to'shade 'any desired part of thewindow, or to leave any dosrodp'art of the window uncovered. If desired, the cord E may be guided to the side of the window, and pass down along' the side-casing, so as to lem-ethe front of .the winde'w more unobstructed, and so that yfile tasscl II or other-balancingweiglit may hang at the side, instead of in front of said window. y u l I I claim as new, and d esircjlo'secure b'yLetters Eatent---l f 1. `Rolling or unrolliri the curtain automatically .by-means eff the cord, and the small axes ef the roller, substantially as described'. i. i v Y 2. Creating an equilibrium hetweeathe-rollor of the window-shade andthe lowerrod F, through the medium` ofh the suspended cord andsmall axes D,' whcreby the shade is 'rolled or unrollod, substantially as herein shown .andde'scribedf "i i. 3. In combination with thesliade s us'pcm'dml-upon axes Dand'tho.lowcnrod F, Iclaim the' .weight H, whereby'said shadeis held at any'desired point, substantially as descri-bedfor the purpose specilied'.'

The above specification of myinvention sigued'by nie, 'this 13th day of'4 January, 1868s l v JACOB B. MOORE.
